Re: Buying new coil packs for 04 DTS

Jim, my understanding is that 2000-2003 they used the ignition cassette with the coils permanently mounted in it. In '04 GM went to what is pictured above with individual serviceable coils. The picture seems to bear that out as they appear to be removable.

Here I go disagreeing again.

What is removable is the so-called "boot"; which is nothing more or less than the long-reach high voltage connection between the coil and the spark plug.

As an editorial aside: I hope to live long enough to witness the day the automotive industry drops the "coil" terminology and starts calling them what they are. TRANSFORMERS. Not much chance of that happening!!

Thanks for the offer, but what is pictured (the entire half side with wire harness) is really what i want (times 2) only because the old wiring ends are pretty fragile and cracked up. So i'm guessing this part is sold like it shows (4 coils, not all 8)
